Be il known citizen of lie l" oit llollyoali, i Stile of De i l invented new and useful linp'rovernenis in Mefnoila for tile Mani rire of Borlle-Closores3 of Wliirli ille following e s'ieciliiiziiien.

lily invention relil le iinprovi'xmente in ine'lzod or process for the niiniiificure of llizit forni of gas-lign.. ifotle .ilesnres; .iliieli consist of :i merel rep carrying.` internally e gasket.

The 'metal cap which l use is of 'ille usual well known foi-1n7 lt is generally annular in shape, lieg :i siilistfinizilly lief; ion and e ilelieniling flange or rim subtizinizilly zilriglit angles to the top, which is iirliipei'l to lie crimped to the bottle top, :mil carriee u lgasket of some enit-able material 'for forming a ges :nul liquid tiglilzjoint between it and the bottle to )i in order their tlze gasket may not be (lisp ecerl in sliign'nrnt in lianilling, or in lie meizliine iif'liirii caps "alle out lle, experience eliowzi that some Incline musi be employed ifor so securely uniing lilies@ two paris that there will be no (langer of their becoming accidentally separated, and my present invention relates, lo an iniprovcfl melliod or process for accomplish ing this end. Heretofore this lios been zu coniplisliefl by :assembling the metallic cap and sealing gasket with a cenieniing medium interposed, then healing the whole with or without the applications oi pressure, the lient icir. en'iployell to fuse the ceineniing material iin-(l the pressure, if pressure be used, to liolil in@ parte in Contact until the fined cemenizing malerizil seis. This method is objectionable for the reason that the Seel.F ing gnske, ii* cli usually contains or treated willi i y cerintcq and generally Curries :i 'consid role quantity of water, is apt to be unduly healed and dried and Lilie substance, willi wliicli it iS treated are evaporated or their nature changed as to lose their inenflei eifiect.. )fly method of overcoming lliese objectionable features corisislis in iii-.st heating llie metal cap, which may or may noil during che process oi' liee* ing, carry the cement-ing medium, and after this inserting tile "islret, it being understood lli-ii there is nl u neally to be a @inenting medium. beiween the gasket and lie ca The el: and cela having 'been assembled. are *M i lily, out not necessarily, subie-ated 3o at Yressure to hold them in close the ceineniing material has rlace of ineiil Cep is frcf nly greasy o pieve-nl". lie ee um from adhering to it prop il heating of the 'metal cap also ve oil' the thin film of grease or lie present., end leave e surface li will be no question of the mening medium adlierinff. The cement- ;snaierial muy be applied directly to the cap or gasket, or il,- i'niiy be carried by a colle of peper or other suitable material wliicli .ie placed between the metal cap and the gasket.

The :accompanying drawings which form parl of this specification and in which simi lar nuineifile of reference indicate similar parte liroiigliout the several views show n nir-ffliine for Carrying ont my process.,

ln i'riese drawings Figure L, is a plan of llie machine and Fig. 2, :i Side elevation o? L n eireular rotating plate furnished 2- for carrying the metal part 3 l me closure. The parte 3 are placed in the pockets 2 in any suitable manner, by lined, fo insieme,

fl a ges burner for heating the plate 1 :mil lire metal parts 3 of the closure. Be-

i l is preferably circular and is i uny convenient manner to bring Y neared calpe '3 to a shifter 5 which sweeps them from plate l to a second rot-ating plate tnislie with pockets 7 similar to the pockets 2 .in pli/ite l. The plete 6 forms part of :i rot-citing head which carries plungers 8, of; nfiteil by springs 97 which engage the giislrer, which nos been placed in the heaed ce; 3 in any convenient manner, by hand for instance, and holds them under pressure until ille cenienling material has set.

1C* is stationary cam for engaging collars 1l on plungers 8 to lift 'diese plungers clear of lie after the ceinenting medium i. A'

'iimigli the clrawings sliow a means for to the process for the manufacture of the closures than to any means for carrying the process out.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

l. In the manufacture of bottle closures composed in part of metal, the methodor process which consists in heating the metal part of the closure, inserting therein While cooling a collet of paper, or other suitable material, coated with a fusible cement thereby fusing the latter, depositing a sealing gasket in the cap on top of the fused cementing medium, and finally applyin pressure `part of the closure, inserting therein While cooling a collet of paper, or other suitable material, coated with a fusible cement there.- by fusing the latter, and finally applying pressure to said parts until they are united.A
